Last September, Serena Williams was struggling to walk to the mailbox. Now, she's into final of Wimbledon after a dominant 6-2, 6-4 win over Julia Goerges.

"It's been a crazy 10 months. I was still pregnant at this time last year. That's something I have to keep reminding myself," Williams said. "Also, going out there, being a mom, is super cool. Knowing that no matter what happens, I have amazing support and unconditional love. It's such a great feeling."

She'll play Angelique Kerber for Grand Slam No. 24. Kerber is one of five women that has defeated Williams in a Grand Slam final. 

The 23-time Grand Slam champion is one match away from equaling Margaret Court's record, and yet that's somehow not on her radar.

"To be perfectly honest, I haven't thought about that this tournament. Not even once actually. In fact, I've probably forget about it," Williams said. "I think that's a good thing because I put so much pressure on myself when I was trying to get to 18. It's just a number."

She's also a little more preoccupied with spending time with her 10-month-old baby girl, Alexis Olympia Ohanian Jr.

The public didn't learn about Williams' medical complications after childbirth until months after Olympia's birth in September. The 36-year-old underwent multiple surgeries after she got a pulmonary embolism and further complications from a C-section procedure that put her life in danger.

If you watched her HBO docu-series, you know the full story really well by now. She let cameras in on everything, including her pregnancy, the hospital delivery, her C-section scar, her complications and her struggles to get back in shape. For an athlete that's often so guarded, she let her fans deep inside her world.  

"It's no secret I had a super tough delivery. I lost count after, like, four surgeries because I was in so many surgeries," Williams said. "Because of all the blood issues I have, I was really touch-and-go for a minute. It was tough. There was a time I could barely walk to my mailbox."

Now she's going to walk out on Centre Court on Saturday for a chance to make history, again.
